CARL HERMANN STAMER, OF HAMBURG, GERMAN Y.

WATER-GAGE.

SPECIFICATION forming part of Letters Patent No. 442,465, dated December9, 1890.

Application filed June 3, 1890. Serial No. 354,151. (No model.) Patentedin Germany March 26, 1889, No. 52,472, and in England June 22,18B9,N0.10,220.

To LZ tof/tom it may concern;

Be it known that l, CARL HERMANN STAMER, a subject of the GermanEmperor, and a resident of l lamburg, in the German Empire, haveinvented certain new and useful Improvements in Valves and Tater-Gages,(for which I have secured .Letters Patent in England, No 10,220, datedJune 22, 41889, and in Germany, No. 52,472, dated March 2G, 1885),) ofwhich the following is a specification.

My invention relates to improvements in valves and water-gages, and theobjects ot' the same are to provide suitable closing devices forlifting-valves, such as plug-valves, and efficient contrivanees forcausing in watergages the steam and water to be instantaneously andautomatically shut off when the glass bursts, and allowing' the closingof the automatically-actin g valves to be with facility obviated whileblowing the steam through the glass tube for cleansing purposes. Iattain these objects by the mechanism illustrated in the accompanyingdrawings, in which- Figure l illustrates a vertical section of aWater-gage constructed according to my invention, and showing, as anexample, my improved closing device adapted for use in any kind oflifting or plug valves. Fig. 2 is ahorizontal section on the line Il Il,and Fig. 3 a horizontal section on the line III HI of the upper part ofmy improved water-gage, Fig. l illustrating the arrangement of thesteampassages to permit the communication of the socket connected to theboiler with the gageglass, while Fig. 4 represents a horizontal sectionon the line IUI IHI, Fig. l, ofthe lower part of my improved water-gage.

Similarletters refer to si mi lar pa rts th roughout the several views.

The main part of my invention relates to the novel method by which anenduring tight closingof the valves is insured, and this is performed bythe employment ot' aplng tot soft copper or other soft metal, thesharp-edged face ot' which is adapted to establish a tight closing inthe conical seat a of the passage of the tiuid in the valve-casing.-This copper plug tapers toward its free extremity, in order to allow itstight fit inthe conical seat a to be re-established, when necessary, byrenewing its sharp circular edge. As the conical form of the plugdiii'ers from that of its seat in the val ve-casing, and as, further,the renewal of the sharp edge of the plug can easily be effected byturning or filing oit the hollow face of the conical plug, the renewedcircular edge of the latter, on account of its diameter being largerthan that of the eut-oit worn edge, will consequently meet a newuntouched closing-surface in the corresponding seat a, and therefore anenduring tight fitting of the plug in its seat is insured. rlhis closingdevice is particularly applicable for water-gages and gage-cocks of thestyle illustrated in the drawings. The upper part of the water-gage,Figs. l. to 3, consists of a easing g, having attached to its rear sidethe socket-piece k with iiange 7.1 or a suitable screw-plug, and to itsfront,opposite to the socket-piece if, the cleaning-aperture, which isclosed by the screwplug o. The valve-spindle s, adjustable by means of ascrew-thread so in the nut m, and tightened outwardly through thestuing-box p, is provided so as to traverse the cleaning device at anangle of about thirty degrees. To the internal extremity of the spindles is connected the above-described plug-valve t of soft copper or othersoft metal, which iits in the conic bore (l of the passage to thesteamgenerator. Sidewise oi' the socket 7e is provided thc tube-inutiler, and in front of the latter the valve-chamber if, communicatingthrough the passage d with the casing g and through the passage c withthe tubc-mutiier, thereby allowing the steam to flow through the upperpart of the water-gage to the gageglass, in the direction indicatedbythe arrows. The valve-chamber r is provided between the aperture d andpassage c with a partition L", having a bore or opening a', tightlyclosed by means of the sharp-edged copper plug t', which is guided byaid of its stem in the closin g-serew j", and adapted to be taken outtherewith for cleaning or other purposes.

lYhen the gage-glass bursts, the steam, rushing through the casing g,causes the valve t to be instantaneously closed, while, in ordertoobviate the closing of the valve when the steam blows through theglass-tube for cleaning the same, the screw-spindle g', provided TOO inthe upper part ol' the valve chamber, is slightly turned, therebyarresting' the copper plug` t.

The automatic closing of the lower part of the water-gage, which part isof the saine construction with the analogous portion of the up' perpart, except that the. chamber g is in direct communication through thepassage (Z2 with the respective tube-Inutile yr and the valve-chamber eomitted, is effected by means of the copper plug` t2, which is adaptedto [it in a bore or openingi e2 of a passage in the inuffle 1", and isguided either in the bow of a closing-screwf, as the plug-t in the upperpart of the water-gage, or in a branch f', of the casingot`thelowerdelivery-valve 71,. The tight closing of the latter, whichbeing', for sake of elearness, represented as turned for ninety degrees,is likewise insured by means of a copper plug t3, provided on thevalvespindle s and extending into a conic bore CL3 ot the casing. f

Having,` now fully described my invention,

what I claim, and desire to secure by Letters Patent, is-

As an improvement in water-gages, the casing having a socket-piece 7c, alower passageway connecting with said socket-piece, an upper passage c,and a diaphragm having` a bore or opening, the valve-chamber n, thevertically-disposed valve having a tapering end designed to fit saidbore or opening", the screw -spindle g', designed to engage said valve,and the horizontally-disposed valve titting` a conical seat in thepassage from said socket-piece, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two witnesses, this 29th day of April, i890.
